I'm trying to install SQL Server 2000 on a newly-installed Win 2003
Server box. My disk is SQL Server SP 2. I got the error message
stating that I couldn't run SQL Server less than SP 3, but I
downloaded the patches from Microsoft's website figuring I'd install
SP 2 off the disk and then install the SP 3 from the download.

Trouble is, when I try to install SP 3, it can't authenticate the
login I give it, either the Windows logon or the sa password, to
actually install SP 3.

I've double-checked the passwords and permissions, and the Windows
logon _should_ be working, and the sa password is definitely what I'm
using in the SP 3 installation program, but no luck.

Any help would be appreciated.
